Train speed optimization
open-in-new
<p>Train speed optimization, also known as Zuglaufoptimierung, is a system that reduces the need for <a href="/facts/Train/0mkFQDg9">trains</a> to brake and accelerate, resulting in smoother and more efficient operation. </p><p>While train speed optimization needs some technical infrastructure, it is more of an operational concept than a technical installation. One can relatively easily implement train speed optimization using for instance <a href="/facts/Cab_signalling/KHhlJLe3">cab signalling</a> (e.g. using <a href="/facts/ETCS/ABXTw78g">ETCS</a>), but the presence of a cab signalling system does not necessarily mean that it uses train speed optimization. Train speed optimization may also be implemented using conventional <a href="/facts/Railway_signalling/yK37bHt7">signalling</a>. </p>
